Abstract

A trash can liner is disclosed which evenly distributes the load across the sealed bottom portion thereof. The liner includes a body portion which is formed from a tube of coextruded, thermoplastic film.
The tube includes edge portions which are folded inwardly towards the center line of the tube along first and second fold lines. The tube is also folded along its center line prior to sealing to form a construction including eight overlapping walls of approximately equal width. A pair of heat seals extend through each of the eight overlapping walls at one end of the tube, the heat seals being separated by an unsealed area.
